9336. PCR. Genetics. Lactose intolerance (13910 T>C, blood)
Description
Primary lactose intolerance is a genetic disease manifested by deficiency or complete absence of lactase in the body (an enzyme that breaks down lactose – milk sugar). The disease is provoked by changes in the gene that codes for the production of lactase in the body.
Identification of these changes allows diagnosing primary lactose intolerance and differentiating it from a secondary (or non-genetic) form of the disease, as well as assessing the risk of developing osteoporosis.
When and who needs the test?
- symptoms of lactose intolerance (bloating, stool disorders, nausea, etc.);
- differential diagnosis of lactose intolerance and other diseases of the gastrointestinal tract in adults;
- determining the likelihood of developing osteoporosis;
- assessing the likelihood of lactose intolerance in young children to prevent bowel disorders.
